Today, physicists, chemists, and materials scientists around the globe seem to have immersed themselves in the world of nanostructures, which promises us materials for unique lasers, remarkably efficient solar cells, quantum computers, and high-resolution monitors. But how efficiently can modern physics explain all the processes taking place in the nanoworld? Do theoretical and experimental physicists have enough reliable and simple tools to solve fundamental problems concerning nanomaterials? These questions are the subject of the special issue of the international peer-reviewed journal Nanomaterials". Its guest editor is Anatoly Fedorov, the head of the International Research and Education Center for Physics of Nanostructures and a professor at ITMO University.
An international group of scientists from Russia, Germany and France, including those from ITMO University, conducted a large research at the intersection of materials science and photonics. The research is dedicated to the study of a hybrid nanostructure, a plasmonic golden sponge (Au), the pores of which are filled with crystalline silicon (Si). The peculiarity of this material is that when excited by a laser beam, nanostructures generate broadband radiation which covers the visible range of the spectrum and partially the near-infrared range. The hybrid nanostructure can be used in broadband near-field microscopy. The results of the research and its application prospects have been published in the Nanoscale journal.
A group of scientists from ITMO University, including one Master’s and one PhD student, has proposed a new method for quick cooling-down of surfaces using perovskite and light nanoparticles. In the future, this principle can be used to cool nano-lasers in optical chips, increase the life of solar panels, and create smart glass. The article was published in the journal Nanoscale.
Ksenia Mosina, a Master’s student at ITMO University’s SCAMT Laboratory, went to Canada as part of her student exchange program to participate in research on the synthesis of gold core-shell nanoparticles for biosensing and photocatalysis. The results of the research were published in Nanoscale. In this interview with ITMO.NEWS, Ksenia shares about her experiences and the skills she acquired in the Canadian laboratory.
Young scientists from ITMO University proposed a new type of optical nano-sensors. Their operating principle is based on the interaction of light in thin films: a similar effect can be observed in soap bubbles. Such sensors can be quickly manufactured using an inkjet printer and special ink made of titanium dioxide. In the future, the sensors can be used for rapid biomedical analysis. The results are published in Nanoscale.
An international team of physicists has discovered a new type of curved light beams, dubbed a “photonic hook”. Photonic hooks are unique, as their radius of curvature is two times smaller than their wavelength. This is the first time that such a small curvature radius of electromagnetic waves has been recorded. A photonic hook can be used to improve the resolution of optical scanning systems, as well as to control the movement of nanoparticles, individual cells, viruses or bacteria. Results of this research were published in Optics Letters and Scientific Reports.
Researchers at ITMO University have unveiled a new approach to printing luminescent structures based on nanoparticle ink. The unique optical properties of the ink were achieved by means of europium-doped zirconia. Particles of this material were proven to be useful in manufacturing glowing holographic coatings with a high degree of protection. Notably, the developed approach enables the fabrication of custom holograms by means of a simple inkjet printer. The results of the research were published in RSC Nanoscale.
